In the manufacture pecially fabrics knit on a machine of the riblace typefor use vin the manufacture of hats and caps, wherein the yarn may be of artificial sllk or may be sotreated as to impart more or less stifnessto the fabric, it has been found, usually or always, that the fabric,

when cut, presents edges that readily fray and that the severed pieces will not lie fiat but will assume a form more or less curved or distorted.v a

The object of the present invention is to provide a fabric which may be knit on a ma- Vchine of the type specifiedl and which may be cut into blan s of any form without sub.- sequent frayin at the ends, Which blanks, regardless of` t eir size and shape, will not curl or distort but will lie at on a plane surface. r

' A face'view of a fabric em yin the invention is shown inthe figure of the rawing A machineof the type adapted to knit my improved fabric is one in whlch the different threads composing the fabric to be knit produce a Warp and weft effect in the fabric, this being eiected-by-'causing one or more threads to extend only 'in a general longitudinal direction to form a Warp effect while one or more threads are, as the knitting proceeds, moved laterally and 'produce a weft effect. The fabric shoWn in the figure is of this character, its novelty residing in the Way in Which the threads are interloo d and interlaced to impart to it the desirab e characteristics hereinbefore specified. The gvure is not onlyA enlarged, but is somewhat distorted` in order to make' the structure and mode ofiknitting more readily understood by one skilled ini the art; the mild distortion causing the drawin of the fabric to present an appearance' s' 'par to, butnotz'precisely identical with, that Aof the fabric itself.

The specific fabric shown, which embodies,

direction of extension of all the threads is longitudinally of the ',fab'ric. Threads a and` b are interlooped to form the Warp eect. Threads c extend v laterally, in su essive of knitted fabrics, es' courses of knitting, to form the weft effect. I

Each thread a extends forward through a loop in course 1, forward and through a loop in course 3, back throu` h the said loop in course 1 and-forwardto orm a loop in course 2, forward through the said loop in course 3, forward through a loop incourse 5, and so on.

Each thread b extends forward through a loop in course 2, forward and through a loop in course 4, back through said loop in course 2 and forward to form a loop in course 3, forwardthrou h'ithe said loop in. course 4, forward throug a loop in course 6, and so on.

Thus, thread a forms the loops in alternate courses which may be arbitrarily called the even numbered courses and extends throu h loops in the odd numbered courses, While threads a and b to the second Wale beyond and thence back a ain to vthe rst Wale. Thus, selecting one o the threads c', it extends from the bights of adjacent loops in courses 1 and 2 of Wale 12 to the bights of adjacent loops in l courses 2 and 3 of Wale 10. Another thread c'extends in a similar manner in the same course from Wale 13 to Wale 11'. Another thread c extends in a similarmanner in the same course from Wale. 14 to Wale 12; Yand'so on.` Thethree threads specified, in the next course, extend respectively from Wale .10 to 12, from Wale to 14.

Looking at the fabricV on the face thereof i shown in the drawings; each thread c extends ut under all the loops over all 'the threads where the latter extend through the loops.

Specifically, each thread cfis, in one course,l

confined between thread a and each loop formed by thread b andis, in the next' course, confined between thread b andieach loop formed by thread 11..' i

AV fabrlc with threads interlooped and inf lterlaced as above describedcan be-cut alo any lines to form a blank of any shape an such blank does not curl or' kink-but returns a flat form when placedo'n a plane surface.

11 to 13 and from Wale A12 y What we claim and desire to protect by Letters Patent is:

1. A knitted fabric consisting of sets of threads; each set of threads comprising a plurality of loop-forming threads each of which forms loops in non-adj acent courses of a Wale and extends through loops formed by the other thread 'in other courses of the same Wale, and comprising also a weft-effect thread extending laterally in one direction between non-adjacent wales of one course and in opposite directions between the same nonadjacent wales of an adjacent course, said arrangement extending substanially throughout the fabric.

2. A knitted fabric consisting of sets of threads; each set of threads comprising a plurality of loop-forming threads each of which forms loops in non-adjacent courses of a Wale and extends through loops formed by the other thread in other courses of the same Wale, and comprising also a weft-effect thread extending laterally in one direction between non-adj acent wales of one course and in opposite directions between non-adjacent wales of another course, the last named thread being confined between a loop and that part of a loop-forming thread which extendsy through such loop, said arrangement extending substantially throughout the fabric.

3. A knitted fabric consisting of sets of threads; each set of threads comprising a plurality of loopeforming threads each of which forms loops in non-adjacent courses of a Wale and extends through loops formed by the other thread in other courses of the same Wale, and comprising also a weft-effect thread extending laterally in one direction between non-adjacent wales of one course and in opposite directions between the same nonadjacent wales of an adjacent course, the last named thread being confined between a loop formed by one of the loop-forming threads and that part of the other loopeforming thread which extends through such loop, said arrangement extending substantially throughout the fabric.

In testimony of which invention, we have hereunto set our hands, at Philadelphia, Pennsylvania, on this 4th day of March, 1929.
